I am trying to waterproof hide glue and have already tried various formulas that I have found on line which gave me limited success. They either weakened the adhesion of the glue or only worked to to make the stuff somewhat water resistent, but not at all waterproof. Now I am actually thinking about getting some formaldehyde which I here will do the job, either by exposing the backing to the fumes in an enclosed area or by putting some into the mix. From what I here this will in fact make it impervious to water. Does anyone have experience with this or have any thoughts about the matter?
